Will my drive shaft bolt right up to the tranny end or what is going to happen with that? Thanks Steve

The rear end will bolt in as long as they are both leaf spring trucks. It is a little wider but the stock square body rear end track width is narrower than the front so the extra width actually brings the tires out so they line up with the front a little better. The gearing is probably better and the transmission already has the proper speedo gears to match it so your speedometer should read closer to right.

You at least need the brake switch off the 89 pedal assembly and should take the throttle cable. I don't think the pedal mount bracket will fit but the pedals themselves might. You will have to test fit them to see.

Your driveshaft will probably be way to long to fit so it will have to be shortened. The transmission yoke is most likely the same spline count and should fit. The 89 driveshaft might be a closer fit and will have the right rear U-joint to match up with the rear end if you swap it out. I don't know how the wheel bases compare to know for sure if the 89 part will be long enough.
